We perform simulated observations on the outputs of
up-to-date SPH simulations in a \Lambda cold dark matter
cosmology, at redshifts of 3-6. We determine the
luminosity function over the rest-frame UV magnitude range
MAB(1700Å) ~-24 - -16 in simulations with a
variety of box sizes. We highlight the evolution of the
luminosity function for z=3-6, and compare the simulation
results with those of recent surveys of Lyman-break
galaxies. We use a variety of values for galactic dust
extinction covering the range E(B-V) = 0.0-0.3 for use in
comparison with observational data. Overall, our simulated
UV luminosity functions show good agreement with
observational data when moderate amount of dust extinction
E(B-V)~0.15 is assumed.
